Plotline

Kirk arrests Harry Mudd for selling "love crystals" to miners on the planet Motherlode. Mudd escapes, kidnapping Chapel and stealing a shuttle. Meanwhile his crystals cause havoc on the ship. Can Kirk track Harry down and reverse the effects of the potion?

Analysis

Again we rehash TOS, this time by bringing Harry Mudd back. I don't mind Mudd's re-appearence as he was already a recurring character. The story has no real content as such; it mostly serves as an excuse to have the Enterprise crew behave out of character again, something done several times in TOS.
